TABS: BLACK MOLD BLUES

So there is a 0h1 simultaneous with two 1s2's. In my mind the 0h1 feels more like a slide, use my video for reference.

Remember H3 means third harmonic (5th fret) but this is just two octaves above the open string. You can play an open string instead if you struggle with the harmonic, I used to play it that way.
